NEUTRAL GROUNDING REACTORS

AREAS OF USAGE

Reducing single phase earth fault currents which occur in M.V. electrical networks to prevent damages on transformers and generators

Reducing temporary over voltages occurred by braking instantaneous fault current

Providing long-life for switchgear

Reducing step voltages to a harmless level for personnel

Neutral Grounding Reactors are single phase reactors generally connected between ground and neutral of transformers, generators. Neutral Grounding Reactors are used in order to limit maximum fault current to a value which will not damage the equipment in the power system, yet allow sufficient flow of fault current to operate protective relays to clear the fault.
